It stands on a short field. On the primer I etch up to 1.5 atm - it goes softly and smoothly. On the highway: 2-2.2 atm, does not leave a rut, there is no noise, the roll is good. In the mud - an honest average, but IMHO on clay it's worse to get stuck. A wet road is good, a turn on wet pavement with clay after a KAMAZ truck from the side of the road is winding, but it is easy to catch, after ten or so the sky and the earth are stuck. Price / quality IMHO on the top five.
